The use of dark horse programmers----structures (Range, point, Size, Rect)

1.NSRange: (range)

2.nspoint\cgpoint (nspoint equivalent to Cgpoint): (Position: X, Y)

• There are two ways to set up point:

1.NSPoint point = Nsmakepoint (100,56);

2.NSPoint Point2 = Cgpointmake (40,63);

• Convert the Nspoint type to a string type:

3.nssize\cgsize (nssize equivalent to cgsize): (Size: Long, wide)

• There are two ways to set up a size:

1.NSSize size = nsmakesize (20,30);

2.NSSize size2 = Cgsizemake (20,30);

• Convert the Nsszie type to a string type:

4.nsrect\cgrect (nsrect equivalent to CGRect): (Position: X, Y, size: long, wide)

• There are two ways to set size:

1.NSRect rect = Nsmakerect (23, 40, 80, 90);

2.NSRect rect2 = CGRectMake (10, 20, 60, 70);

• Another way to create a nsrect:

• Origin: Cgpointzero = = Cgpointmake (0, 0);

• Convert the Nsrect type to a string type:

5. Determine if a point is within a region (Nsrect):
